Carb-free bread might sound like just another Internet hoax, but the "cloud bread" you might've heard about lately is for real. These little bread loaves (which are also gluten-free) emulate the look of hamburger buns without loading on the extra carbs. Still sound too good to be true? Sure, it's not actual bread, but it might be the next best thing when you're craving a burger, sandwich, avocado toast or nearly anything you'd usually eat with normal bread.
